Understanding split views
Split views refer to the ability to access two forms side by side on a mobile device. This feature is mainly provided for tablet devices, as most phones can only display one window/form at a time.
A split view is composed of a "left pane" and "right pane". In programs, the panes are implemented with window objects displaying forms, which are controlled by parallel dialogs.
This feature is only for mobile platforms.
Split views (controlled by parallel dialogs) are typically used to browse the application data, while modal dialogs are used for data input in a single form. An application based on split views will start with parallel dialogs, and switch to a simple modal dialog when the user chooses to edit application data. Parallel dialog handling is suspended by the runtime system, when a modal dialog executes. For details about parallel dialogs compared to modal dialogs, see What are dialog controllers?.
If the application displays several split views simultaneously, implement a navigator pane, to let the end user switch between the different split views.
